The 4 Stages of Swallowing: Biomechanics Bolus Movement

With a normal swallow, food and liquids move from the mouth into the esophagus directed by a precise sequence of coordinated muscle movements. In order to adequately describe the biomechanics and bolus movement during swallow, the 4 stage model was developed: Oral Prepatory Stage, Oral Transit Stage, Pharyngeal Stage, and Esophageal Stage. The animation describes each of these stages which provides the necessary background knowledge in order to understand when swallowing is abnormal.
